assertSame()

assertSame()

assertSame(mixed $expected, mixed $actual[, string $message = ''])

當(dāng)兩個(gè)變量 $expected 和 $actual 的值與類(lèi)型不完全相同時(shí)報(bào)告錯(cuò)誤，錯(cuò)誤訊息由 $message 指定。

assertNotSame() 是與之相反的斷言，接受相同的參數(shù)。

assertAttributeSame() 和 assertAttributeNotSame() 是便捷包裝(convenience wrapper)，以某個(gè)類(lèi)或?qū)ο蟮哪硞€(gè) public、protected 或 private 屬性作為實(shí)際值來(lái)進(jìn)行比較。

Example?A.37.?assertSame() 的用法

<?php
class SameTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertSame('2204', 2204);
    }
}
?>

assertSame(object $expected, object $actual[, string $message = ''])

當(dāng)兩個(gè)變量 $expected 和 $actual 不是指向同一個(gè)對(duì)象的引用時(shí)報(bào)告錯(cuò)誤，錯(cuò)誤訊息由 $message 指定。

Example?A.38.?assertSame() 應(yīng)用于對(duì)象時(shí)的用法

<?php
class SameTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertSame(new stdClass, new stdClass);
